Liquid Fluoride Thorium Reactors will lessen the need for an expanded national grid. The National Electric grid is at the breaking point. It needs to be expanded, but neighborhood resistance is building in many areas where they need an expanded grid the most. The grid is also sensitive to terrorism activities.
As we can see the national grid is extensive. It is also under severe strain at peak demand.

A way to lessen the dependency on the national grid is to sprinkle it with many small to medium sized Thorium Nuclear Power generators. They can be placed on barges in rivers and along the coast where the need is greatest, giving the grid maximum flexibility to respond in case of an emergency. (To be fair, the Texas grid is separately controlled from the rest of the grid.
